Essay 1: Adaptive Radiation Adaptive radiation is the fundamental mechanism responsible for the great variety of animal and plant species observed today and that dominated the Earth surface in the past (MacDonald, 2003). In simpler terms, adaptive radiation is the diversification of species to occupy a wide range of ecological niches. The term ecological niche describes the role of a species within its surrounding environment; its interaction with the biotic and abiotic environmental factors;…

Based from the first two chapters of River Out of Eden, Richard Dawkins lays out the foundation about the concepts of ancestry, genes, reproduction and evolution. He highlighted on many key factors such as from Chapter 1 that our ancestry is composed by the river of DNA, and that the concept of the Mitochondrial Eve is considered as more poetic than the mythology of Genesis from Chapter 2. Specifically, Dawkins makes his point by explaining that the purpose of our existence is primarily based on…

We did that by deeply observing our bodies and then determining whether we have the following traits. PTC, Darwin’s ear point, ear lobe attachment,…

started, what it’s is made up of, and if it was inevitable or rare. He begins to talk about how life is the result of physical and chemical processes. Smith then quotes a quote from a man named Steven Gould. “Any replay of the tape of evolution would lead evolution down a pathway radically different from the road actually taken.” He explains that as life is a product of physical and chemical processes then if we were to replay everything from the beginning,…

In the novel, The Story Telling Animal, Jonathan Gottschal, the author, uses facts and his own life experiences, as seen through his daughters’ creative play to support his argument that the powerful nature of story-telling is what makes us human The author opens his second chapter with the powerful imagination of his young daughters.

because humans cannot fully comprehend why the world is orchestrated in the way it is, “....many non-Christians and even some Christians, consider divine creation an absurdly and anti-intellectual concept.” If we cannot fully comprehend Creation, it is not a problem nor an anti-intellectual concept. Creation is not meant to be fully comprehended by humans; our job is to have faith and believe. The dilemma with viewing Creation as a problem correlates into saying faith is a problem. Evolution…

This excerpt from the book Literature and its Times has an in depth analysis of Victorian Life and provides a brief biography of Robert Louis Stevenson. According to Moss, Stevenson was very involved with Calvinism in his childhood which contributed to an active imagination.

For example, Moss shows how religion inspired Stevenson’s writings: “Furthermore, Dr. Jekyll’s resignation and…

There are many theories that are biosocial that we have learned about, however; I will be focusing on three theories. The two theories I chose intrigued me, and made me think more about how society was when the theories were developed and how these theories may or may not apply to today's societal views. I feel it is important to be able to see how thing have and haven’t changed in societies eyes when it comes to a person’s biology. Not only on biology, but also how the theories are affected by…

Evolutionary synthesis is described as “a unified theory of evolution that combines genetics with natural selection” (Larson 2014:42) and points out that natural selection, ,gene flow, mutation and genetic drift are the four causes for evolution. Gene flow focuses on the spread of new genetic information between populations of the same kind (Larson 2014:44). This really is how genes spread from one population to the next. There are many factors that come into place when looking at gene flow.…

By gaining an understanding and examining evidence associated with each of these three theories it becomes clear that the most logical and truthful of the three is the theory of Chemical Evolution. Before delving directly into the first theory, one must understand Darwin’s theory of natural selection because it is a theory that the majority of scientists take to be true. The scientific community agrees on natural selection because the evidence…
